WHY PLOUTO IS NOT A PLANET

Answer»

tion:The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not MEET the three criteria the IAU uses to DEFINE a full-sized planet. Essentially Pluto MEETS all the criteria except one—it “has not cleared its neighboring region of other objects.”
